Toby:
If your camera has a stabilzer function try it with it off and on.
Some cameras work better one way or another.
Autofocus can mess with ya.
If you have glare on the inside of the window it can focus on that point rather than in front or your car, or focus on some part of the hood..
that can make the road look shakey too.
If all else fails....
I have a camera mount from I/O Port that is top notch that you could borrow for the event.
What day are you guys going again?
